[gentoo-hardened] clone(2) blocks for 30 seconds

[Alex Efros]

Hi!

Please take a look at
http://serverfault.com/questions/460429/clone2-30-sec-delay-in-apache

I didn't think it may be related to hardened but I've just found this in
kernel logs:

2012-12-23_20:45:19.15938 kern.alert: grsec: From 75.101.174.3: Segmentation fault occurred at 000014e2 in /usr/sbin/apache2[apache2:5346] uid/euid:81/81 gid/egid:81/81, parent /usr/sbin/apache2[apache2:1391] uid/euid:0/0 gid/egid:0/0

I can't check this right now - I have to wait until this bug happens again -
but looks like this bug happens after about 10-20 such records in logs.
So, maybe grsec break something in kernel while handling these segfaults
which in turn result in delay in clone(2)? Or maybe I have to run memtest. :(
